Title: Improvements in and relating to power-transmitting systems
IPC: B60B11/00
Filed: 1959-11-20
Abstract: 912,641. Universal joints; linkwork. ANCIENS ETABLISSEMENTS ALBARET, S.A. DES. Nov. 20, 1959 [Nov. 21, 1958; Sept. 2, 1959], No. 39540/59. Classes 80 (2) and 80 (3). [Also in Groups XXXI and XXXII] A drive between an annulus 20, Fig. 1, rotating on a fixed axis, and a shaft 3 rotating about a swinging axis, is transmitted by a number of pusher members 40-43, Fig. 2, having partspherical ends engaging corresponding surfaces on opposed faces of a spider 21, on the shaft 3, and of projectors 30, 31 on the annulus. As shown, the shaft 3 carries the wheels 1, 2 of a vehicle such as a compacting roller and is supported in bearings 4, 5 in a casing 8 mounted for swinging on trunnions 11, 12 rotatable in bearings in a casing 13 fixed to the vehicle chassis. The annulus 20 is supported on bearings 16, 17 in the fixed casing 13 and is driven by chain or toothed gearing (not shown). Alternatively the bearings 16, 17 may be omitted and the annulus 20 be supported solely by three pairs of pusher members and by lateral guides. When the annulus 20 rotates clockwise torque is transmitted to the spider 21 by the two pusher members 40, 42, the members 41, 43 being under no load. The annulus 20 is, however, mounted slightly eccentric of the centre of oscillation of the shaft 3 and spider 21 so that at any instant only one pusher member is under load, the load being taken wholly by the member 40 for one half of a revolution, and then wholly by the member 42 for the next half of a revolution. The pusher members 40-43 pass through an oil bath in the lower part of the fixed casing 13, the casing 13 and shaft 3 being sealed by ball-and-socket joints 53, and each member 40-43 has at each end a spring- loaded piston serving to separate the partspherical surfaces and allow the entry of oil when the respective pusher member is under no load. The angular extent of swinging of the shaft 3 is limited by an abutment plate, Fig. 5 (not shown), bolted to the casing 13 and having two sloping edges engageable with the swinging casing 8. The abutment plate may, if desired, be replaced in inverted position so that a straight edge engages the casing 8 to prevent any swing- ing thereof.

Title: Apparatus for measuring the presence of a weak acid or a weak base in a liquid
IPC: G01N27/06
Filed: 1975-09-29
Abstract: In order to reduce the effort and time required, there is arranged, for the purpose of measuring the electrical conductivity of the flowing sample, a conductivity measuring cell (40'') in the through-flow lines. Present in the same line, downstream of the conductivity measuring cell (40'') there is a fluid inlet for the addition of a controlled amount of reagent to the flowing sample. The measurement of the electrical conductivity of the flowing sample after the reagent addition is carried out by means of a second conductivity measuring cell (40) downstream of the liquid inlet. For the purpose of adding a controlled amount of liquid to the flowing sample, a second fluid inlet is arranged in the through-flow line downstream of the second conductivity measuring cell (40). The measurement of the electrical conductivity of the flowing sample after the addition of liquid is carried out by means of a third conductivity measuring cell (40') in the through-flow line downstream of the second liquid inlet. A computer (41) is connected to the three conductivity measuring cells (40'', 40, 40') to provide an output signal which represents the acidity or alkalinity of the flowing sample and which can be processed in any way required. The appliance is particularly suitable for fully automatic monitoring of a water supply, sampling being carried out continuously or controlled by timers. <IMAGE>

The rod 14 is secured at one end to a plate 15 which carries slide blocks 10, 11 which are disposed in grooves 8, 9 in a cup-shaped member 5 secured to the input shaft 3. The other end of rod 14 carries an eccentric lug 17 on which is secured a ball 18 retained by a plate 21 in a socket 19 formed in a slide member 20. Rotation of a knob 65 causes rotation of a sleeve 48 carrying the nut 47 and axial movement of slide 20, thereby causing axial movement of rod 14 to vary the amplitude of reciprocation of the output member 43. In the position shown, the rod 14 is parallel to the axis of cup-member 5, and it may be located in that position by a ball 70. Thus the upper limit of reciprocation remains fixed. The sleeve 48 is rotatably mounted with respect to a support 60 by a resilient bearing formed by a triangular frame comprising resilient rods 51, 52 and 53. The ends of the rods are held in the support 60 whilst their middle points co-operate with a circular groove 64 in the sleeve 48.
